Breakwater cast-in-place pile pore-forming and pouring method
The invention provides a bulwark cast-in-place pile pore-forming and pouring method. The method comprises the steps that step1, preparation before construction is conducted, specifically, after an excavator is used for digging downwards by 3 m, a foundation trench is leveled, concrete cushion layers are poured between an inner pile casing and an outer pile casing and within the range of 2 m outside the outer pile casings, after maintenance is conducted for 2 days, two sections of outer pile casings are arranged according to a positioning axis, intermittent welding is adopted for the connecting positions of the pile casings, and slurry pouring openings are cut in the upper surfaces of the outer pile casings; a slurry pouring port is symmetrically cut on the upper surface of the inner pile casing and the outer pile casing; then, the outer pile casing is lowered, after the outer pile casing is lowered, the center of the pile position is rechecked, and after rechecking is confirmed, earthwork is backfilled between the inner pile casing and the outer pile casing; step 2, holes are formed in a first large layer; step 3, holes are formed in a second large layer; step 4, holes are formed in a third large layer; step 5, a pile casing is lowered; step 6, holes are cleaned; and step 7, pouring is conducted. According to the method, the construction problem in cast-in-place pile hole forming and pouring can be well solved, and it is guaranteed that the quality of a formed cast-in-place pile can meet the design and specification requirements.
本发明提供一种防波堤灌注桩成孔灌注方法。本发明的方法包括：步骤1.施工前准备：用挖机向下挖3m，平整基槽后，对内外护筒中间及外护筒外2m范围内浇筑混凝土垫层，养护2天后，按照定位轴线下2节外护筒，护筒与护筒连接处采用间断焊，外护筒上表面切割倒浆口；内护筒上表面与外护筒对称切割一处倒浆口；然后下外护筒，外护筒下好后，复核桩位中心，复核确认后，将内外护筒中间用土方回填；步骤2.第一大层成孔；步骤3.第二大层成孔；步骤4.第三大层成孔；步骤5.下护筒；步骤6.清孔；步骤7.灌注。本发明能很好解决在灌注桩成孔和灌注中的施工问题，保证灌注桩成型后质量能满足设计和规范要求。
